eSketch

eSketch is a lightweight software application whose purpose is to help you create and simulate analog circuits that include capacitors, inductors, resistors and op-amps.

The GUI looks straightforward and embeds a side panel from where you can select the objects that you want to add in the circuit. You can move the elements to the desired position using the drag-and-drop support.

You may also have a look at the help manual in case you have any questions regarding the program’s features.

eSketch gives you the possibility to create an analog circuit using different components, such as resistors, capacitors, inductors, om-amps, grounds, potentiometers, transformers, voltage sources, current sources, and voltage probes.

When it comes to editing features, you are allowed to cut, copy, paste or delete the objects, undo your actions, insert user-defined text (that can be customized in terms of font, color and size), and add markers. Plus, you can save the circuit image to BMP or EMF file format.

The tool is able to automatically detect flaws in your design and shows them in a dedicated panel (e.g. a voltage or current source is required). You may zoom in or out of the design, show or hide nodes, grid, and component values, and check out a list with all components included in the design.

eSketch comes with support for different simulation modes, such as Monte Carlo analysis, parameter sweep analysis, pole-zero calculation, multiple voltage probes, input impedance, real and ideal op-amp models, phase, group delay, and sensitivities.

All things considered, eSketch provides a quick and efficient way for helping you design and simulate analog circuits. The utility hasn’t been updated for a while so you can make use of its features especially on older operating systems, like Windows 2K, XP, Vista, 7 and 2003.
